Bernstein and Bernstein-Like Inequalities for Modulation Spaces
نویسندگان
چکیده
It is shown that the modulation spaces Mwp can be characterized by approximation behavior of their elements using Local Fourier bases. In analogy to bases, we show also Gabor frames. We derive direct and inverse theorems describe best linear combinations N terms a given function its modulates translates.

Dense Markov Spaces and Unbounded Bernstein Inequalities
An infinite Markov system {f0, f1, . . . } of C2 functions on [a, b] has dense span in C[a, b] if and only if there is an unbounded Bernstein inequality on every subinterval of [a, b]. That is if and only if, for each [α, β] ⊂ [a, b] and γ > 0, we can find g ∈ span{f0, f1, . . . } with ‖g′‖[α,β] > γ‖g‖[a,b]. This is proved under the assumption (f1/f0)′ does not vanish on (a, b). Extension to hi...
متن کاملOn Bernstein Type Inequalities for Complex Polynomial
In this paper, we establish some Bernstein type inequalities for the complex polynomial. Our results constitute generalizations and refinements of some well-known polynomial inequalities.
متن کاملNorming meshes by Bernstein-like inequalities
We show that finite-dimensional univariate function spaces satisfying a Bernstein-like inequality admit norming meshes. In particular, we determine meshes with “optimal” cardinality for trigonometric polynomials on subintervals of the period. As an application we discuss the construction of optimal bivariate polynomial meshes by arc blending. 2000 AMS subject classification: 26D05, 42A05, 65T40.

متن کاملBernstein Type Inequalities for Quasipolynomials
We prove a Bernstein type inequality for multivariate quasipolynomials and apply it to carry out the following results. (1) The evaluation of the uniform norm for a quasipolynomial on a convex body V/R by that on a measurable subset of V. (2) The estimate of the BMO-norm for a quasipolynomial in terms of its degree and exponential type. (3) The reverse Ho lder inequality with a dimensionless co...
